Work control system for managing operation of power tools, has detector that repeatedly receives signals related to work progress of power tools from power tools at predetermined transmission intervals to detect work progress

Abstract: An intelligent assembly system for a manufacturing process using one or more sensors that provide information for controlling, monitoring and/or evaluating the process... sensors may be mounted on a module assembly and/or on a powered tool device... sensors may sense a vibratory signature and/or electrical current during the process and supply information, such as a data signal, to a software program or other processor for processing... Results... transmitted to an operator and/or graphically displayed... may instruct the operator to continue with the manufacturing process or inspect the process step just completed for possible error.
